My friend lives some 200 miles away but we text via What's App every day. She has stage four breast cancer and has been undergoing gruelling treatment for four years. I check in almost every day to make sure she is ok - she is Christian and very devout. I changed my phone this weekend and I wasn't able to text or send messages. However, when I did get my texts up and running, I discovered the message - Thanks for checking up on me Susan (Susan is not my name and I've no idea who Susan is!!) You're the only one bothering HA HA. I was stunned. When my dad was very ill and dying, she switched off her phone for two weeks due to mental health reasons (I was unaware she had mental health issues!) Then when my dad did die, she missed the frigging funeral as I was unable to contact her. I'm the least confrontational person, but AIBU to reply to this? I've already explained the change of phone, and apologised.
